Fix Set/Map delete on iteration

[Bnaya]

Currently deleting the current iterated item on Map/Set will lead to skip the next item.

To fix that we need:

• Allocate iterator inside the ArrayBuffer
• Update the iterator on delete
• add deallocation of that iterator on iteration end, manual, and on finalizationGroup
  For now its a known limitation

It's a hard-fix, maybe you can work with a append only strategy, and increment a counter to the latest message that wasn't red yet
